I was beginning to think I was the only one that liked taxes, but then I saw Anthony’s post. People who talk about the evils of taxes make, I think, two mistakes:

First, they forget that certain kinds of goods can only be (practically) delivered by the government. Without taxes, our public infrastructure would be nonexistent, which I think even the most libertarian among us would not prefer. Our taxes naturally have to adjust to fit the public needs of our State; otherwise, everyone’s need for public goods will go unsatisfied.

Second, they assume that government spending is by definition inefficient. Admittedly, I’m no economist, but I can certainly speak to my own spending – it’s bloody inefficient. And I think I am not being overpresumptuous in thinking that I’m hardly alone in that. Free markets are good, but not perfect, at allocating resources under certain circumstances. That’s all. Ultimately, the choice whether or not to tax should be made on pragmatic, and not ideological grounds.

I’ve discussed why I think the inefficiency argument is silly. I haven’t explained why I think taxes are fair. Even a flat tax costs the rich much more than the poor, and a progressive tax costs the rich a great deal more than the poor. Why is this fair?

One response is something that Mr. Obama, in fact, offered to Joe the Plumber (the original): if you start out poor and end up rich, it’s the progressive income tax that made that happen; in effect, the tax redistributed wealth from your rich future to your poor present, which in fact enabled your rich future. Lowering tax rates on the rich would be, in effect, pulling up the ladder behind you.

A second is that, in general, wealthier individuals derive more value per dollar of wealth than poorer individuals. This is because the investments of the wealthy are multifarious, because the transactions of the wealthy are complex, because the interests of the wealthy are many – as a result, the various services of the government that ensure all of the transactions and investments add much more value to the rich than the poor.

A third is that, of course, the marginal utility of money to the wealthy is much smaller; as a fraction of their, uh, total utility (is there an economics term for this?), they’re paying as much or less than poor people.
